■Look online. There are lots of tips, videos, and workout plans. Jenna Bergen, Prevention magazine’s fitness editor, recommends dailyburn.com, for $10 a month. ‘‘What’s cool about these sites is if you don’t live in a city and have access to good classes, these give access to top instructors,’’ Bergen says.

■Use apps. Tabata Trainer, a $1.99 interval training app, focuses on high-intensity bursts of exercise. Yog, a free app, helps you plan a run with anyone in the world. Prevention has an iPad app, Flat-Belly Express, for $2.99.

■Check stores, parks departments, and recreation centers for inexpensive classes. Lululemon, Reebok, and Nike stores often offer free yoga and other classes. Senior programs at the YMCA or YWCA can be options. And state and national parks often offer exercise classes.

■Use outdoor gyms. These ‘‘adult playgrounds’’ are usually free. Equipment can include seats with bike pedals, chin-up bars, elliptical trainers, and leg-press machines.

■Check with your employer. See if you can get gym discounts, free nutritionist visits, health coaching, or other perks.

■Walk or run. Walking is the easiest and cheapest workout there is. And it works, says Bergen, who suggests signing up for a 5K to get motivation to stick with it.
